Question

我已经从Christoph Gohlke Unofficial Windows installers安装了scipy和scikit-learn，并且以下命令成功运行且没有错误：

>>> import sklearn
>>> import scipy

然后我将尝试sklearn.datasets.load_digits()函数，如链接文档中所示：

from sklearn.datasets import load_digits

但该行引发了一个错误的抱怨，据我所知，_log_logistic_sigmoid未被发现：

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    from sklearn.datasets import load_digits
  File "C:\Python27\lib\site-packages\sklearn\datasets\__init__.py", line 23, in <module>
    from .twenty_newsgroups import fetch_20newsgroups

    from ..utils.extmath import row_norms
  File "C:\Python27\lib\site-packages\sklearn\utils\extmath.py", line 23, in <module>
    from ._logistic_sigmoid import _log_logistic_sigmoid
ImportError: DLL load failed: The specified module could not be found.

有人遇到过这个错误吗？如何解决？

如果有帮助的话，我在Windows 8机器上使用python 2.7。

Answer 1

通过卸载非官方软件包解决，然后使用以下命令从官方软件包重新安装：

pip install -U numpy scipy scikit-learn

导入sklearn.utils._logistic_sigmoid模块时出错
